Adjusting the pulse frequency controls the level of heat input applied to the weld relative to the weld travel speed.ResultsBetter control of heat input in the weld, resulting in:•Reduced warping and burnthrough on thin materials. •Smaller heat-affected zone – good for thin material.•Smaller bead profile without compromising proper penetration.Easy “Set It/See It” Operation:•Flashing indicator light lets you see the pulse rate before you strike an arc.W e l d i n g C u r r e ntTimePulsed TIG Weld (at 60 amps)Standard TIG Weld (at 60 amps) Smaller HeatAffected ZoneSmaller Bead ProfileMicro-Start ™II Technology aids arc stabilityTHROUGHOUT THE WELD CYCLE – even at the lowest amperage!

276合金介绍简介********公司生产的AL-276合金（UNS N10276）是一种Ni-Mo-Cr-Fe-W合金，是目前广泛应用的耐蚀性能最好的合金之一。
AL-276合金已被广泛应用在苛刻的腐蚀环境中，如化学工业，石油化工，烟气脱硫，纸浆，造纸等各工业领域中。
该合金通过恰当的合金元素的搭配以及杂质元素的控制，使之在焊后态仍具有很高的耐蚀水平。
AL-276合金还具有优良的高温强度和中等的抗氯化能力，但该合金在高温下由于高温脆性相的析出将导致高温脆性。
AL-276合金（UNS N10276)各种形式的产品多年前即被列入ASME锅炉与压力容器VIII第1，第2章中。
该合金可以采用类似于奥氏体不锈钢和其他镍基合金的焊接制造方法进行焊接制造。
值得注意的是，在设备制造期间，应避免材料中碳、硅等元素的增加而引起材料耐蚀性能的降低。
产品形式和应用条件AL-276合金以板、薄板、带的形式供货，可根据要求提供各种焊管。
所有产品均以固溶态供货。

By subtracting secondary turns the same primary amperage willresult in greater secondary output.Again using the 300:5 example, adding 5 secondary turns will require 325 amps on the primary to maintain the 5 amp secondary output, orDeducting 5 secondary turns will only require 275 amps on the primary to maintain the 5 amp secondary output, orThe above ratio modifications are achieved in the following manner.• To add secondary turns, the white lead should be woundthrough the CT from the side opposite the polarity mark.• To subtract secondary turns, the white lead should be wound through the CT from the same side as the polarity mark.WARRANTYThis product is warranted to be free from defects in materials and workmanship for one year.
